Procedure

To a rt solution of tert-butyl(S)-1-((2S,3S)-8-cyano-2-methyl-4-oxo-1-(tetrahydro-2H-pyran-4-carbonyl)-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxopropan-2-yl(methyl)carbamate (65 mg, 127 μmol) in DMF (316 μl) was added 1-(chloromethyl)-2-methoxynaphthalene (31.4 mg, 152 μmol), cesium carbonate (53.6 mg, 165 μmol), and sodium iodide (24.7 mg, 165 μmol). The reaction was stirred at rt for 1 h, then diluted with EtOAc, washed with H2O and sat. aq. NaCl, dried over Na2SO4, filtered, and concentrated. The crude material was purified by flash chromatography to provide tert-butyl(S)-1-((3S,4S)-7-cyano-1-((2-methoxynaphthalen-1-yl)methyl)-4-methyl-2-oxo-5-(tetrahydro-2H-pyran-4-carbonyl)-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxopropan-2-yl(methyl)carbamate (75 mg, 87%) as a white solid. MS m/z 706 (MNa)+.
